The HWC is dedicated to the conservation and recovery of Hawaii's vulnerable and <a href="http://inhabitat.com/interactive-almost-extinct-calendar-raises-awareness-of-endangered-species/">endangered native wildlife</a> and hopes to achieve this through hands-on treatment, research, training, science education, and cultural programs.

The center consists of three integrated and sustainably designed components: a wildlife care and response facility, an interpretive and outreach lanai and native species garden, and an open-air education <a href="http://inhabitat.com/tag/pavilion">pavilion</a>.

An open air staging porch acts as the emergency entrance for injured birds and local school groups can come learn about the center's work in the large open room on the opposite side.

The building's design was inspired by archetypal Hawaiian commercial architecture from nearby towns, but modified for energy efficiency and sustainability.

Slats on the front act as a giant "window" letting in daylight, but protecting from the rain.

The walls of the main treatment facility in the back are clad with locally fabricated corrugated steel.

Natural ventilation and daylighting throughout the space are key design strategies to reduce energy usage.

Rainwater is collected and stored in catchment tanks, then heated with solar hot water, while a rooftop <a href="http://inhabitat.com/tag/solar-power">photovoltaic system</a> provides non-emergency electricity.

<a href="http://ruhlwalker.com/blog/2011/03/the-hawaii-wildlife-center/">Stage 1 of the project</a> was completed in March of 2011 and resulted in a completed exterior shell, outdoor areas and a roughly built interior.

As of August, the center had finished fundraising in order to complete construction and over 100 people volunteered to plant native vegetation around the center.

The <a href="http://www.hawaiiwildlifecenter.org/donate.htm">HWC relies on donations</a> from generous individuals to run the center as well prepare for emergencies such as oil spills and disasters to help wildlife recover.
